To measure and compare the Panasonic Lumix FZ8's corner sharpness we photographed the Enhanced Digital Camera
Resolution Chart with it and a number of rival super-zoom models, each using their
best quality JPEG and default image tone and sharpening settings.

We set each lens to their widest and longest focal lengths and
tested them at various apertures.
The crops are taken from
the extreme lower left corner of the chart and presented here at 100%. Note the TZ3 only has two aperture settings.

Zoomed-out to wide angle, the Panasonic Lumix FZ8 delivers pretty sharp results in its corners, even with the aperture wide open. It doesn't suffer from the coloured fringing of its rivals here.

Zoomed-into its longest focal length, the FZ8 exhibits some fringing, but again the results are superior here to its main rivals. To be fair though, despite offering a powerful 12x optical zoom, the FZ8 neither zooms as wide or long as the Olympus SP-550UZ or Sony H9.
